Lot Number:... Stock Number:... Date of Manufacture:... Quantity of Primer in Container:... Information and Warnings as may be required by procurement... documents... Manufacturer s Name and Address:... Design Guide: For guidance on the usage of this Paint for Various application/environments and temperature range reference shall be made to IPSETP100 "Paints" 9.3 Directions for Use The following directions for use shall be applicable and shall be supplied with each container of paint: Directions for Use of Red Lead, Iron Oxide, Raw Linseed Oil and Alkyd Primer This paint is intended for use as a primer over hand cleaned steel in atmospheric exposure; it will perform better if the steel is power tool cleaned, blast cleaned or pickled. All rust scale, loose rust, loose mill scale, and loose or nonadherent paint shall be removed. Oil and grease shall be removed to the fullest extent practical, as residues of oil and grease remaining on the surface will result in decreased paint performance. Mix paint thoroughly before use. If the pigment has settled, pour off most of the liquid into a clean container, thoroughly mix the pigment with the remaining liquid, taking care to scrape all the pigment off the bottom of the can. Gradually add the poured off liquid and mix thoroughly. Mixing may be made easier by transferring contents to a larger container or by pouring the primer to and from another container. Examine bottom of container for unmixed pigment, screen paint before applying. Thin paint only if necessary, using only mineral spirits. For brush application under normal conditions, no thinning should be necessary. For spray application, add up to one liter of thinner per eight liters of primer when necessary. 7
May 1993 IPSMTP 115 Apply by brush or spray to the specified film thickness or, if none is specified, to at least 50 microns dry or approximately 75 microns wet. The surface to be painted shall be dry; the surface temperature shall be at least 3 C above the dew point; and the temperature of the air shall be over 4 C. Do not paint outdoors in rainy weather or if freezing temperatures are expected before the paint dries. Allow primer at least 24 hours drying time in good weather before recoating. 9.4 Directions for Safety The following directions for safety shall be supplied with each container of paint: Paints are hazardous because of their flammability and potential toxicity. Proper safety precautions shall be observed to protect against these recognized hazards. Safe handling practices are required and should include, but not be limited to the provisions of SSPCPA Guide 3, "A Guide to Safety in Paint Application "and to the following: Keep paints away from heat, sparks, and open flame during storage, mixing, and application. Provide sufficient ventilation to maintain vapor concentration at less than 25% of the lower explosive limit. Avoid prolonged or repeated breathing of vapors or spray mists, and prevent contact of the paint with the eyes or skin. Clean hands thoroughly after handling paints and before eating or smoking. Provide sufficient ventilation to insure that vapor concentrations do not exceed the published permissible exposure limits. When necessary, supply appropriate personal protective equipment and enforce its use. This paint may not comply with some air pollution regulations because of its hydrocarbon solvent content. Ingredients in this paint which may pose a hazard include Red Lead, hydrocarbon solvent, and lead drier. Applicable regulations governing safe handling practices shall apply to the use of this paint. 8
